GRISWOLD, OE NASHVILLE, TENNESSEE a HEATER Application tiled February 12, 1929. Serial No. 339,360.

The present invention relates to improvements in heaters and more particularly to a heater that is designed to employ gas as a j a series ot vertically disposed air tubes -open at their upper and lower ends, the products of combustion being adapted to circulate around the air tubes for heating the air passing upwardly therethrough, additional means -being arranged within the easing to etect the circuitous How o1 the products ot combustion around the air tubes.

Another important object is to provide a heater of` the above mentioned character wherein heat radiating' tins are associated with each air tube. l

Another object is to provide a gas heater of the above mentioned character wherein the gas burner is provided with supplemental air passages that are arranged concentrieally with respect to the gas discharge orifices formed in the pipe ot the burner.

Still a further object is to provide a gas burner of the above mentioned character that will at all times be positive and etlicient in its operation, the same being t'urther simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed.

Other objects and advantages will become apparent during the course ot the following description.

In the accompanying drawing, forming a part ot this specification. and in which like numerals indicate like parts throughout the same:

Figure 1 is a vertical sectional View through the gas heater embodying my invention: Y

Figure 2 is a sectional view taken approximately on the line 2 2 of Figure 1 looking in the direction of the arrows;

Figure 3 is a sectional View taken approximately on the line 3-3 of Figure 1 looking downwardly Figure 4 is a silnilar section taken substantially on the line 4-4 of Figure 1 also looking downwardly;

Figure 5 is a transverse section taken substantially on the line 5-5 ot' Figure 1 looking in the direct-ion ot the arrows, and

Figure G is a sectional view taken approximately on the line tof Figure Il.

ln the drawings wherein tor the purpose ot' illustration is shown the preferred embodiment ot' my invenlirui, the numeral 1 designates a substantiall)v rectangular shaped casing that is open at its top anfbbottom.

Suitable supporting legs 2 space the open lower end of the casing from the ground as suggested in Figure l. A grating 3 is arranged on the top oi the casing.

The. lower portion ot' the t'ront side ot the casing is set inwardly as indicated at 4e in Figure l and a swinging door 5 is associated with this set in portion and radiant tiles 6 are mounted in the door in the manner well known in the art. lt will also be observed that upon referring to Figure l that the door 4 when in a closed position is disposed at an incline and above the burner a unit denoted generally by the reference character 7.

This Vburner unitl includes a base plate 8 on which is arranged the longitudinally extending gas chamber 9 that is of substantially rectangular contiguration and cross section as clearly indicated in Figure G. The top of the gas chamber 9 is Jformed with the gas discharge openings 10. the same being arranged in staggered relation as more clearly shown in Figure 4.

This gas chamber 9 extends upwardly through the bottom otl the casing for disposition within the lower front portion of the casing and the base plate 8 engages with the adjacent portion of the bottom ot the casing as clearly indicated in Figures 1 and G. The gas chamber 9 extends for substantially the Ventire, length of the casing and a gas pipe 11 tive gas/outlet openings 1() as also clearly shown in Figure 6. The air tubes 12 are of a smaller diameter than the gas outlet openings 10 and the gas emitted through the openings 10 commingles with the air discharged from the upper ends of the respective tubes 12 to provide a blue flame when the burner is ignited.

A series of substantially rectangular shaped air tubes or liues 13 are arranged vertically in the rear portion f the casing, the same extending at the lower ends through the openings provided therefor in the bottom of the casing while the upper ends extend through similar openings provided therefor in the top 'of the casing and in the present instance, I have shown live of such air tubes or flues as being arranged within the casing 1, the ,o same belng spaced with respect to each other. Formed on theinner opposed faces of the longitudinal sides of each air iue are the verticallydisposed radiating'ns 14the inner opposed edges of the respective pairs of Afins g being spaced from each other as more clearly shown in Figures 4 and 5.

The purpose of these fins is also well known in4 the Vart and therefore detaill description of the same is believed unnecessary. Form- )o in g a salient part of the'present invent-ion are the horizontally disposed baiileplatesl that are arranged in vertically spacedl relation within the casing -1 and upon referring to Figure 1 it will beobserved' that t-he lower- I6 most baiie plate extends from the front side of the casing to a point adjacent the rear side thereof and the uppermost baflie plate extends from the rear side to a pointadjacent the front side.

This is for the purpose of effecting a circuitous flow of the products of combustion around the air ues or tubes 13 before being discharged out of the casing through the outlet 16 provided at the upper 4portion of -the rearlside of the casing.

It is also to be understood that each baffle plate is cut out to accommodate the several vertically disposed air iues.

In Figure l thereis shown by the arrows how the products of combustion pass around the air flues and also the direction of the iow of the air through the Vflues 13 and obviously as the air` passes upwardly through these ues, the same will be heated by the products through the. grading 3 arranged at the, top -ofthecasin the fins further secure a maximum amount-of radiation from the air ues. 4Also the air tolbe heated will not be contaminated i by'anv fuel-gases and due toits simplicity, the

,substantially the full width of the casing and of combustion and the heated air is emitted f heater can be constructed ata very Iowicostfand yet be strong and durable.

While I have shown the preferredembodiment of my'invention, it is to be understood that various changes in' the size, shape-and arrangement of parts' may be resorted, to without departing from the spirit ofnthe in! vention and the scope ofthe appended claims.

Having thus described my invention, what I claim as new is:

1. A heater comprising a casing having a door-suporting portion extending inwardly and upwardly at an inclination to the bottom of the casing, air `flues extending longitudinally through said casing and spaced from said door supporting portion, a gas Y burner within the space between the said llues and said door supporting portion, and a door unit of radiant tiles mounted in said door supporting portion and adapted when in closed position to provide an inclined reflectorl` above the burner.

2. A heater comprising a casing having 'a bottom' burner receiving opening extending l adjacent one side thereof and having the lowi f er portion of said side set inwardly to provide a door holding portion disposed above and inclined to the said burner'receiving opening, a gas. burner extending upwardly through said bottom opening for substantially the full length thereof, a series of relatively spaced air tubesextending vertically through the said casing and arranged in a row parallel to the said opening, said air tubes being rectangularl in cross'section and respectively disposed with their lower ends at right angles to said burner, a horizontally disposed balile integrally connected'to a side of the said casing above the said intake portion and terminating in spaced relation to the oppositeside of the casing, said baille bein cut out to accommodate the several air tu es, and a door mounted in said door holding portion and inclined therewith, said door having va radiant deflecting face above the said burner for deflecting the heated gases transversely between the said air tubes.A

In testimony whereof I aix my signature.

JACOB TELLER. 115
